> Sorry for not answering earlier; but the degradation looks quite concerning indeed. A minor difference (e.g. 3-4%) would be ok, but we seem to be getting a 30% slowdown in some of these cases. I agree that the performance change seems severe. I am not sure why adding ints to a second buffer would affect the performance that much. I also was getting wildly different values between runs on the same branch sometimes almost a 50% change so I am not sure how reliable any of those numbers really are. I can play with it some to see if I can figure out what is going on. -- This is an automated message from the Apache Git Service.
